Communicating location specific emergency information to a mobile device

ABSTRACT

An occurrence of an emergency situation pertinent to people presently located within a venue can be identified. Responsive to identifying the emergency situation pertinent to the people located within the venue, a first level of security clearance assigned to a user located within the venue, and a present location within the venue of a first mobile device of the user, can be automatically determined. A route, from the present location within the venue of the first mobile device to an exit of the venue, which does not require the user to be assigned a second level of security clearance that is higher than the first level of security clearance for the user to traverse the route, also can be determined. An emergency alert and an emergency plan for exiting the venue can be automatically communicated to the mobile device, wherein the emergency plan for exiting the venue describes the route.

BACKGROUND

The present invention relates to mobile communications and, moreparticularly, to emergency related mobile communications.

Emergency procedures, exit locations, and other potential lifesavinginformation oftentimes are provided in commercial buildings, but areusually accessible as diagrams or depictions, posted in limited places,or as videos posted in limited places at limited times. As an example,in certain municipalities, public transportation vehicles, such buses,taxis and airplanes, are required to present to passengers emergencyexit procedures using schematic images or videos. Such schematic imagesand videos oftentimes lack detailed explanation and are general innature. In addition, they usually do not present a step-by-stepalgorithm customized based on the specific location, situation oremergency. Moreover, passengers do not necessarily have proceduresreadily available if needed. For example, a hotel may post an emergencyexit schematic diagram in hotel rooms, but once customers leave theirhotel rooms, they may not find any other emergency exit diagrams whileattempting to leave the hotel during an emergency.

U.S. Pat. No. 7,098,787 discloses “[a] mobile device receives proximitylocation information from at least one location identification beacon. Auser of the mobile device dials an emergency telephone number when anemergency occurs. Dialing the emergency telephone number enables theproximity location information to be transmitted to an emergency callcenter.” During an emergency, however, users, may find it distractingand cumbersome to have to dial an emergency telephone number.

U.S. Pat. No. 8,755,767 discloses a “method and system provide a currentphysical geographic location for a mobile device (e.g., buildingaddress, a building floor, a room on a building floor, campus,enterprise, city, state, region, country, continent, etc.), in anemergency situation such as an accident, fire, terrorist attack,military incident, etc. and forward the physical geographic location toa legacy 911 network or a Emergency Services IP networks (ESInet).” Suchoperation, however, does not help guide people safely out of astructure.

U.S. Pat. No. 7,720,431 discloses a “mobile wireless system (10)includes a transmitter such as a satellite (18) that broadcasts wirelesssignals such as boundaries for specific areas to a mobile receivingdevice (22). Mobile receiving device (22) may include an antenna (26)and a mobile receiving device (28). A locating receiver (50) is used togenerate locating signals so that a determination may be made to thelocation of the mobile receiving device. When the location is outside anarea of interest the area of interest may be extended to provideservices to the mobile device. Emergency information is broadcast to afirst area. An emergency announcement indicator is also broadcast into afirst area and an area outside the first area. The location of themobile receiving device is compared to the first area and the emergencyinformation is displayed when the location is within the first area.”Thus, a user must be located in proximity of where the emergencyannouncement indicator is broadcast in order to receive the emergencyannouncement.

FIG. 1 is a block diagram illustrating an example of a communicationsystem 100. The communication system 100 contains at least onecommunication network 110. The communication network 110 is the mediumused to provide communications links between various devices and dataprocessing systems connected together within communication system 100.The communication network 110 may include connections, such as wire,wireless communication links, or fiber optic cables. The communicationnetwork 110 may be implemented as, or include, any of a variety ofdifferent communication technologies such as a Wide Area Network (WAN),a Local Area Network (LAN), a wireless network, a mobile or cellularnetwork, a Virtual Private Network (VPN), the Internet, the PublicSwitched Telephone Network (PSTN), or the like.

The communication system 100 also can include an emergency notificationsystem 120 and a plurality of beacons 130, 132, 134, each of which maycouple to the communication network 110. The communication system 100also can include a plurality of mobile devices 140, 145. In one aspectof the present arrangements, one or more of the beacons 130-134 can beimplemented as wireless access points, wireless routers, microcells orthe like, and the mobile devices 140, 145 can couple to thecommunication network 110 via the beacons 130-134 to both receive andtransmit messages via the communication network 110. In another aspect,the beacons 130-134 can be implemented as devices configured to transmitradio frequency (RF) and/or infrared (IR) messages that are detectableby one or more of the mobile devices 140, 145, but the beacons 130-134need not be configured to relay messages transmitted by the mobiledevices 140, 145 to the communication network 110.

The emergency notification system 120 may be implemented as one or moredata processing systems (e.g., servers), each including at least oneprocessor and memory, executing suitable operational software to supportcommunication of emergency notifications to one or more of the mobiledevices 140, 145. For example, the emergency notification system 120 canhost an emergency notification application 125.

One or more of the mobile devices 140, 145 can include a respectiveemergency notification client 150, 155. An emergency notification client150, 155 can be a stand-alone application executing on a respectivemobile device 140, 145, or integrated into an operating system or otherapplication executing on the respective mobile device 140, 145. By wayof example, the emergency notification client 150 can be implemented asa service executing on the mobile device 140. In one arrangement, forexample an arrangement in which the beacons 130-134 are wireless accesspoints or wireless routers, the emergency notification client 150 candetect the mobile device 140 establishing network presence on a network(e.g., a subnet) to which the beacons 130-134 provides network access,and monitor messages received by the mobile device 140 via the wirelessaccess points or wireless routers. In another arrangement, the emergencynotification client 150 can monitor beacon signals generated by thebeacons 130-134 and received by the mobile device 140. Regardless,responsive to receiving a message or beacon signal indicating anoccurrence of an emergency situation pertinent people presently locatedwithin a venue, the emergency notification client 150 can implement anynumber of various processes responsive to such messages/signals, as willbe described. The venue can be a building, a hotel, a motel, a stadium,a store, a shopping mall, an aircraft, a vehicle (e.g., a bus), awatercraft, an amusement park or the like.

In operation, the emergency notification system 120 can detect anoccurrence of an emergency situation pertinent people presently locatedwithin a venue. For example, the emergency notification system 120 candetect a signal from one or more fire alarms indicating that a fire ispresent in the venue, detect a signal from one or more seismic sensorsindicating that the venue has experienced an earthquake, detect a signalfrom one or more weather sensors indicating that a tornado is present inproximity to the venue, detect a signal from one or more acousticsensors indicating gunshots are fired in the venue, detect a signal fromone or more emergency alarms (e.g., fire alarms, silent alarms, etc.),or the like. In another example, the emergency notification system 120can monitor information generated by news and/or social media websites,emergency response services, etc., and detect information that indicatesan occurrence of emergency situation pertinent people presently locatedwithin a venue.

Responsive to detecting an occurrence of an emergency situationpertinent to people presently located within the venue, the emergencynotification system 120 can communicate to the mobile device 140, aswell as other mobile devices, an emergency alert 160 via one or more ofthe beacons 130-134. The emergency alert 160 can be communicated to themobile device 140 via one or more of the beacons 130-134, and can beconfigured to be presented by the mobile device 140 to the user to alertthe user to the emergency situation, for example via a display and/oroutput audio transducer of the mobile device 140. Accordingly, themobile device 140 can present the emergency alert 160 to the user. Theemergency alert 160 can provide contextual information pertaining to theemergency situation. The contextual information can, for example,indicate the nature of the emergency, actions to be taken by the user,precautions to be observed by the user, and the like.

In one arrangement, the emergency notification client 150 cancontinually monitor for beacons signals and/or messages. Responsive todetecting the emergency alert 160, the emergency notification client 150can automatically present the emergency alert 160 on the mobile device140. If the mobile device 140 presently is in sleep mode, the emergencynotification client 150 can automatically take the mobile device 140 outof sleep mode to present the emergency alert 160. In anotherarrangement, the emergency notification client 150 can present theemergency alert 160 responsive to detecting a user input on the mobiledevice 140. For instance, the emergency notification client 150 canpresent the emergency alert 160 responsive to the user launching a webbrowser on the mobile device 140. In a further arrangement, responsiveto the beacon 130 detecting the mobile device 140 attempting to accessthe communication network 110 via the beacon 130, the beacon 130 canintercept an HTTP request communicated by the mobile device 140 andre-direct the HTTP request to a particular website hosted by theemergency notification system 120 presenting the emergency alert 160.Such website can respond to the HTTP request by communicating one ormore HTTP responses that include the emergency alert 160, and the webbrowser on the mobile device 140 can render the emergency alert 160 onthe mobile device 140.

Further, in lieu of or in addition to the emergency alert 160,responsive to detecting the occurrence of the emergency situation, theemergency notification system 120 can communicate to the mobile device140, as well as other mobile devices, location specific emergencyinformation 165 via one or more of the beacons 130-134. The locationspecific emergency information 165 also can be configured to bepresented by the mobile device 140 to the user, for example via adisplay and/or output audio transducer of the mobile device 140.Accordingly, the mobile device 140 can present the location specificemergency information 165 to the user. The location specific emergencyinformation 165 can provide to the user emergency information that isspecific to the user's location within the venue. For example, thelocation specific emergency information 165 can include one or morediagram or images providing a route for the user to exit the venue, oneor more videos showing the route for the user to exit the venue, or thelike. Such diagram(s), image(s) and/or video(s) also can present to theuser contextual information pertaining to the emergency situation.

The user's location within the venue can be determined in any suitablemanner. In one arrangement, the emergency notification system 120 canstore in a computer-readable storage medium, which may be containedwithin the emergency notification system 120 or otherwise coupled to theemergency notification system 120, information indicating the locationof each of the beacons 130-134. In this arrangement, the locationspecific emergency information 165 can be generated for each of thebeacons 130-134, and the emergency notification system 120 cancommunicate to each of the beacons 130-134 respective location specificemergency information 165 to be communicated to mobile devices that arelocated in proximity to the respective beacons 130-134. For example, ifthe mobile device 140 is located proximate to the beacon 130, the mobiledevice 140 can receive the location specific emergency information 165from the beacon 130. In some cases the mobile device 140 may receivesignals from more than one beacon 130-134. In such cases, the emergencynotification client 150 can be configured to receive and process thesignal from the beacon 130 having the highest strength, and present tothe user the location specific emergency information 165 contained inthat signal.

In another arrangement, for example an arrangement in which one or moreof the beacons 130-134 are wireless access points or wireless routers,the emergency notification system 120 can determine a present locationof the mobile device 140 based on which beacon 130-134 the mobile device140 is communicatively linked, or based on a position of the mobiledevice 140 determined by a global positioning system (GPS) receiver. Inillustration, the mobile device 140 can include a GPS receiver andperiodically communicate to the emergency notification system 120messages indicating the present location of the mobile device 140. Theemergency notification system 120 also can receive information from thebeacons 130-134 relating to a strength of signals communicated betweenthe beacons 130-134 and the mobile device 140 and, based on the strengthof such signals, perform trilateration to determine the present locationof the mobile device 140. Regardless, responsive to determining thepresent location of the mobile device 140 within the venue, theemergency notification system 120 can communicate to the mobile device140 the location specific emergency information 165 that is based on themobile device's present location.

Regardless of how the user's location within the venue is determined,the location specific emergency information 165 can include informationthat is specific to the present location of the mobile device 140, andthus the user. In illustration, the location specific emergencyinformation 165 can include an emergency plan for exiting the venue froma present location of the mobile device 140 within the venue. Forinstance, the location specific emergency information 165 can safelyguide the user from the present location to an exit of the venue. Moreparticularly, the emergency notification system 120 can configure thelocation specific emergency information 165 to present to the user aroute to safely get from the present location to the exit. The route canbe predefined for the present location of the mobile device 140, or theemergency notification application 125 can dynamically determine theroute by processing digitized information indicating passageways withinthe venue (e.g., doorways, openings, hallways, staircases, elevators,escalators, rooms, and the like), nature of the emergency situation,etc.

By way of example, if the emergency situation is a fire in the southside of the venue, the emergency notification system 120 can determinethat the route should not include passageways in the south side of thevenue. Hence, the emergency notification system 120 can automaticallyprocess information related to the emergency situation and informationrelating to the venue to determine a route from the present location toan exit that does not traverse through the south side of the venue, andthat route can be communicated in the location specific emergencyinformation 165. Such route can be considered to be safe for the usersince it does not route the user through the portion of the venue wherethe fire is located. Similarly, if the emergency notification system 120detects gun shots fired in the south side of the venue, or detects thata stairway is collapsed in the south side of the venue (e.g., due to anearthquake, tornado, hurricane, explosion, or the like), the emergencynotification system 120 can automatically process such information todetermine a safe route to get the user from the present location to theexit.

In one aspect of the present arrangements, for example an arrangement inwhich the user is an employee or contractor working in a venue that is asecured facility, the emergency notification system 120 also can store,or otherwise access (e.g., from an active directory) user securityprofiles and information indicating user level of security clearancesthat are required for users to access various passageways in the venue.

By way of example, assume that the secured facility includes variouspassageways that are restricted to users having a particular level ofsecurity clearance. The user of the mobile device 140 may not have alevel of security clearance required to access all passageways in thesecured facility. Thus, when determining the route from the presentlocation of the mobile device 140 to an exit, the emergency notificationsystem 120 can demine a level of security clearance assigned to the userand determine a route that does not require the user to be assigned alevel of security clearance that is higher than that level of securityclearance in order for the user to traverse the route. In this regard,the location specific emergency information 165 generated by theemergency notification system 120 can describe a route that does notinclude passageways for which the user does not have an assigned levelof security clearance to enter. Such an arrangement can ensure that theuser is able to safely reach an exit without being blocked by a door toa passage way for which the user does not have the proper level ofsecurity clearance to access.

In another aspect of the present arrangements, the location specificemergency information 165 generated by the emergency notification system120 can describe a route that includes only passageways that do notrequire the user to be assigned a level of security clearancewhatsoever. In yet another aspect of the present arrangements. Theemergency notification system 120 can interface with one or moresecurity systems in the venue to disable security requirements otherwiserequired for users to enter various secure passageways within the venue.For example, the emergency notification system 120 can interface withthe security system(s) to unlock doors or configure the doors to becomeunlocked for any user presenting a user identification that isrecognized by the security system(s) and/or the emergency notificationsystem 120. Such an arrangements can ensure that the user is not blockedfrom accessing passage ways the user may need to traverse to safelyreach the exit.

In another aspect of the present arrangements, rather than the emergencynotification system 120 providing the emergency alert 160 and/orlocation specific emergency information 165, the beacon 130 canstatically store the emergency alert 160 and/or location specificemergency information 165. Responsive to the beacon 130 receiving amessage or other signal from the emergency notification system 120indicating the occurrence of the emergency situation, the beacon 130 canbegin transmitting the emergency alert 160 and/or location specificemergency information 165 to be received by mobile devices, such as themobile device 140. The beacon 130 can repeatedly transmit the emergencyalert 160 and/or location specific emergency information 165 until thebeacon 130 receives a message or other signal to stop transmitting suchinformation.

In another aspect of the present arrangements, the beacon 130 canreceive updates to the emergency alert 160 and/or location specificemergency information 165, for example from the emergency notificationsystem 120 and/or one or more other systems, and the beacon 130 canupdate the emergency alert 160 and/or location specific emergencyinformation 165 accordingly. Responsive to updating the emergency alert160 and/or location specific emergency information 165, the beacon 130can begin transmitting the updated emergency alert 160 and/or locationspecific emergency information 165 in lieu of the previous emergencyalert 160 and/or location specific emergency information 165.

In further aspects of the present arrangements, the mobile device 140can be configured to share the emergency alert 160 and/or the locationspecific emergency information 165 received from the emergencynotification system 120 with one or more other mobile devices, such asthe mobile device 145. For example, the emergency notification client150 can be configured to detect reception of the emergency alert 160and/or the location specific emergency information 165 by the mobiledevice 140 and share such with the mobile device 145. In illustration,responsive to receiving the emergency alert 160 and/or the locationspecific emergency information 165, the mobile device 140 can establishan ad hoc communication link with the mobile device 145, for example aWiFi® communication link, a mesh network communication link and/or apersonal area network (PAN) communication link.

In such an arrangement, the emergency notification client 150 can beconfigured to, in response to the mobile device 140 receiving theemergency alert 160 and/or the location specific emergency information165, automatically initiate the mobile device 140 to broadcasts signalsrequesting communication links to other mobile devices, such as themobile device 145. The emergency notification client 155 executing onthe mobile device 145 can be configured to recognize such communicationsignals generated by the mobile device 140 and automatically initiateprocesses on the mobile device 145 to establish an ad hoc communicationlink between the mobile device 140 and the mobile device 145. Responsiveto the ad hoc communication link being established, the mobile device140 can communicate to the mobile device 145 the emergency alert 160and/or the location specific emergency information 165. Moreover, themobile device 145 can function as a hotspot, relaying communicationsexchanged between the mobile device 145 and the beacon 130, or betweenthe mobile device 145 and the communication network 110.

In accordance with the above example, the mobile device 145 can receivefrom the mobile device 140 the emergency alert 160 and/or the locationspecific emergency information 165 even though the mobile device 145 maynot be able to receive signals and/or messages from the beacons 130-134,which may be due to any number of reasons. For example, the WiFi®transceiver and/or cellular network transceiver of the mobile device 145may be unable to communicate with the beacons 130, 134, while the PANtransceiver still is operative. Nonetheless, the mobile device 145 maybe able to receive the emergency alert 160 and/or the location specificemergency information 165 via the PAN transceiver.

In a further arrangement, the beacon 130 can receive a distress signalfrom the mobile device 145, for example via a mesh network establishedamong the mobile device 145 and the mobile device 140 and other mobiledevices. Responsive to receiving the distress signal from the mobiledevice 145, the beacon 130 can communicate the distress signal to themobile device 140 and/or one or more other beacons 132, 134 for sharingwith other mobile devices. The emergency notification client 150executing on the mobile device 140 can present the distress signal tothe user of the mobile device 140. Accordingly, the user of the mobiledevice 140 can take action to aid the user of the mobile device 145.

Additionally, the beacons 130-134 can be members of the mesh networkestablished among the mobile devices 140, 145, or the beacons 130-134can form their own mesh network. Thus, if one or more of the beacons130-134 lose connectivity to the communication network 110, otherbeacons can act as relays for the affected beacons. In illustration, ifthe beacon 130 loses connectivity to the communication network 110, thebeacon 132 can serve to relay communications between the beacon 130 andthe communication network 110.

FIG. 2 is a flow chart illustrating an example of a method 200 ofcommunicating to a mobile device location specific emergencyinformation. At step 205, an occurrence of an emergency situationpertinent to people located within the venue can be identified. At step210, responsive to identifying the emergency situation pertinent to thepeople located within the venue, an emergency alert and locationspecific emergency information can be automatically communicated to afirst mobile device. The location specific emergency information candescribe an emergency plan for exiting the venue from a present locationof the first mobile device within the venue, wherein the locationspecific emergency information is configured to be presented by thefirst mobile device to a user of the first mobile device to safely guidethe user from the present location to an exit of the venue. At step 215,emergency propagation information can be automatically communicated tothe first mobile device. The emergency propagation information can beconfigured to be processed by the first mobile device to initiate thefirst mobile device to establish a communication link with at least asecond mobile device and communicate from the first mobile device to thesecond mobile device the emergency alert and the location specificemergency information.

FIG. 3 is a block diagram illustrating example architecture for theemergency notification system 120 of FIG. 1. The emergency notificationsystem 120 can include at least one processor 305 (e.g., a centralprocessing unit) coupled to memory elements 310 through a system bus 315or other suitable circuitry. As such, the emergency notification system120 can store program code within the memory elements 310. The processor305 can execute the program code accessed from the memory elements 310via the system bus 315.
